Forage production and productive performance of Nellore heifers in agrosilvopastoral systems

Agrosilvopastoral system is a type of production that involves the soil-forage-animal interface, both of which are benefited by the system. Hence, the present study evaluated the effects of agrosilvopastoral system on the quantitative and qualitative characteristics from pasture, and the animal performance during the feeding period of Nellore heifers. The treatments included: Soil-forage-animal – 357 eucalyptus trees per hectare (LFA14x2m); Soil-forage-animal – 227 eucalyptus trees per hectare (LFA22x2m); and Soil-animal – Five native trees remaining per hectare (CON). The forage used was Brachiaria brizantha cv. BRS Piatã and having as trees planted the Eucalyptus urograndis clones H 13. Treatment effects (P 0.05) for average daily gain, while in November period, LFA14x2m treatment showed the lowest value (P 0,05) para la ganancia diaria promedio, mientras que, en noviembre, el tratamiento LFA14x2m tuvo el valor más bajo (P0,05) para ganho médio diário, enquanto no período de novembro, o tratamento LFA14x2m apresentou o menor valor (P
